Firefox segfault on startup

[MastaG]

I've built Firefox with the latest meta-rust/meta-clang/meta-llvm but it crashes when trying to run it. I'm using: GDB_BACKEND=wayland:

Hmm, it's reproduced also on my build.

core-image-sato on Virtual Box. I didn't follow recent changes so I don't know yet whats wrong.

Hmm, it's reproduced also on my build.

Now I've confirmed that I can build workable binary when I use Rust 1.43 (meta-rust:7f235b6f8973cc5269448375f2a8f9867bb2a369). I don't yet test other versions.
